Toward Service-aware Flow Visualization over OpenFlow-based Programmable Networks
Sungho Shin, JongWon Kim · Proceedings of the Asia-Pacific Advanced Network · 2011
Next-Generation Internet applications demand inherent flexibility and programmability from the underlying network. OpenFlow-based programmable network substrate, as a potential solution, provides the required support to enable network innovations by separating the intelligent control plane from the data-path processing. Several visualization tools have been designed in the context of OpenFlow to facilitate the effective management of programmable flow-centric network. However, most existing tools are still limited in supporting interactive visualization of flows. In this paper, we propose an attempt, called as service-aware flow visualization in programmable networks, which can interactively map the flows onto services. The proposed tool helps us to visually identify (i.e., separate) selected flows from all lists of flows (i.e., flowspace) and to monitor the status of selected flows.
